S200A incorporates major hardware and software technology driven developments. A completely new optical chamber design is proven in extensive testing to be more efficient, less liable to is proven in extensive testing to be more efficient, less liable to false alarm due to dust and insects and less susceptible to fault in high air velocities or back pressure. Extensive hydrodynamic modelling has confirmed the greater efficiency of the new chamber and housing shape combination. Large-scale integration of the all-new electronics, through the fully automated surface mount PCB assembly, coupled with in-line testing through the manufacturing process, laser PCB cutting along with a completely new compound of plastic offers i.mproved quality and reliability All S200A detectors are environmentally friendly and meet the WEEE and RoHS legislative requirements, minimising end of life disposal costs, and are mechanically and electrically backwards c. ompatible with existing devices.

• Available with or without short circuit isolation • Isolator per device allows faster, more precise fault finding • Rotary decade address switches • Ivory colour to harmonise with the modern built environment • 100% mechanical and electrical backwards compatibility • New base design to complement the detector and ease installation and wiring
